WSL Ubuntu中Cargo Rust openssl环境变量未设置

Question

我已经尝试过安装和重新安装pkg-config和libssl-dev。看起来在安装时没有设置openssl环境变量。其他所有帖子都建议安装pkg-config和libssl-dev，但这在这里不起作用。有什么建议吗？

我认为这可能与WSL有关，因为它在完整的Ubuntu安装上运行良好。

  Failed to find OpenSSL development headers.

  You can try fixing this setting the `OPENSSL_DIR` environment variable
  pointing to your OpenSSL installation or installing OpenSSL headers package
  specific to your distribution:

      # On Ubuntu
      sudo apt-get install libssl-dev
      # On Arch Linux
      sudo pacman -S openssl
      # On Fedora
      sudo dnf install openssl-devel

你安装了哪个版本的openssl？这可能与https://github.com/sfackler/rust-openssl/issues/1448#issuecomment-814218122有关。 - b1_

所以，这里是否曾经达成了实际的解决方案？如果是，你能分享一下吗？ - code_dredd

正如评论所述, OpenSSL 3.x 可能不兼容，但您可以安装最新的 1.1.1 版本：

# latest March 2023 release 

ENV OPENSSL_DIR="/opt/openssl"

curl "https://www.openssl.org/source/openssl-1.1.1t.tar.gz" \
  --output "/tmp/openssl.tar.gz"
mkdir --parent "/tmp/openssl"
tar \
  --extract \
  --file="/tmp/openssl.tar.gz" \
  --strip=1 \
  --directory="/tmp/openssl"
( \
  cd "${TMP}/openssl" \
  ./config \
    --prefix="/opt/openssl" \
    --openssldir="/opt/openssl" \
  make && make install \
)

注意：

• 1.1.1 正在积极维护，截至2023年3月报告的漏洞数量已经减少。
• 3.x 版本最近存在漏洞。

因此，如果可能的话，现在坚持使用 1.1.1 也许更为明智。
